Multi-bhendi mapurisa light source system
Basic chimiro uye musimboti we-multi-band light source
A multi-band light source is an optical system inokamura chiedza chichena chinobudiswa nechiedza mumabhendi akasiyana neseti imwe chete kana maviri emafirita emavara, yozoburitsa kuburikidza negwara rechiedza.Iyo inonyanya kuve nezvikamu zvishanu: mwenje sosi, sefa system, inobuda system, control display system, uye cabinet.(Ona Mufananidzo 1 wechimiro).Pakati pavo, iyo mwenje sosi, sefa system, uye yekubuda system ndiyo yepakati zvikamu zve-multi-band light source, izvo zvinotarisisa kushanda kwechiedza sosi.Iyo mwenje sosi inowanzotora xenon mwenje, indium mwenje kana mamwe simbi halide marambi ane yakanyanya kupenya.Iyo mafirita sisitimu inonyanya kureva iyo color filter, kune akajairwa akavharidzirwa mafirita emavara kana emhando yepamusoro bhendi-pass interference color filters.Kuitwa kwekupedzisira kuri nani kupfuura iyo yekare, iyo inonyanya kuderedza kucheka-kubvisa bandwidth yechiedza chemavara, ndiko kuti, monochromaticity yechiedza chemavara inovandudzwa zvikuru.Iyo yakajairwa kuburitsa wavelength kufukidzwa ndeye 350 ~ 1000nm, kusanganisira yakawanda yemitsara inotaridzika mune refu-wave ultraviolet, inooneka mwenje uye pedyo-infrared matunhu.
Kushandisa musimboti we-multi-band light source
1. Fluorescence uye multi-bhendi chiedza zvinyorwa
Kana maerekitironi eextranuclear achifara uye achisvetukira kunzvimbo yaari kufarisa, maerekitironi ari mukufara haagadzike uye anogara achisvetuka achidzokera pasi nesimba rakaderera.Munguva yekusvetuka, simba rakagamuchirwa richabudiswa nenzira ye photons..Chiitiko chekuti chinhu chinonakidzwa kusvika pakunakidzwa mushure mekuvhenekerwa nefotoni yeimwe wavelength, uyezve inosvetuka ichidzokera kune yakaderera simba mwero nekuburitsa fotoni yeimwe chaiyo wavelength.
Inonzi photoluminescence phenomenon, uye nguva yeupenyu yephoton inowanzobudiswa iri pasi pe 0.000001 yechipiri, iyo inonzi fluorescence;pakati pe 0.0001 ne 0.1 sekondi, inonzi phosphorescence.Kana chinhu chichigona kuzvifadza uye kugadzira fluorescence pasina kunze kwechiedza chinokwezva, zvinonzi chinhu chine intrinsic fluorescence.Imwe mamiriro efluorescence ndeyekugadzira masaisai emwenje ane mafungu emwenje akasiyana kubva kumafungu echiedza ekutanga (kazhinji mapfupi-wave excitations kuti abudise mafungu marefu) pasi pekunakidzwa kwekunze kwechiedza, uye macroscopic kuratidzwa ndeyekuburitsa imwe ruvara mwenje.Iyo yakawanda-bhendi mwenje sosi inogona kupa kwete chete inverse mwenje sosi yekutarisa intrinsic fluorescence, asiwo inosimudzira mwenje sosi.
2. Kuparadzaniswa kwemavara musimboti
Nheyo yekuparadzaniswa kwemavara ndiyo inodiwa pakusarudzwa kwakaringana kwebhendi rewavelength (ruvara rwechiedza) uye sefa yemavara eiyo multi-band light source.zvinoreva kuti nekusarudza mimvuri.
